TestNG @AfterMethod Annotations

@AfterMethod is one of the TestNG Annotations. As the name defines, @AfterMethod is executed after each test method within a test class. Suppose there are n test methods within a test class, then n times @AfterMethod annotated method will be invoked. This annotation allows developers to specify various actions to be taken after test methods are run.

Let's understand the @AfterMethod annotation through an example.

Step 1: In a Maven Project, create a TestNG Class that contains @AfterMethod.

After_Method.java

Now, let's explain what this code does:

• Package Declaration: The code is in the com.geeksforgeeks.test package.
• Imports: The code imports annotations and classes from the TestNG framework (org.testng.annotations.AfterMethod and org.testng.annotations.Test).
• After_Method Class: This is the main test class. It contains test methods and setup method.

afterMethod (@AfterMethod)

• This method is annotated with @AfterMethod, indicating that it should be executed after each test method in the class.
• It prints this " @AfterMethod will be executed after execution of each test method" statement.

Test Methods (@Test):

• Each test method is annotated with @Test, indicating that it is a test case.
• There are five test methods: firstMethod(), secondMethod(), thirdMethod(), fourthMethod() and fifthMethod().
• Each test method prints their respective statement.
• After performing the operation, the result is printed to the console.

Step 2: Now, we create the AnnotationsTest.xml file to configure the After_Method class.

Step 3: Run the After_Method file. Right click on the After_Method and move the cursor down to Run As and then click on the TestNG Suite.

As we can observe in above code, the execution of different tests or methods is in proper order. First fifthMethod() Test is executed, then firsthMethod() test, after that secondMethod() and at the end thirdMethod() will be executed.
